I am a postdoc working in algebraic geometry in the group of Jungkai Alfred Chen at National Taiwan University. Before I was a PhD student of Stefan Kebekus at the University of Freiburg. Here is my CV.

My research interests are birational geometry and derived categories of algebraic varieties.

Research interests

Birational classification of algebraic varieties and derived categories of algebraic varieties. More specifically:

  • Campana's birational classification program and differential forms therein.
    (See this talk for more details.)
  • Semiorthogonal decomopositions and their relation to the minimal model program.
    (See this talk for more details.)

Other academic activities

LaTeX templates

  • My basic LaTeX templates. They are a bit minimalistic, and they include a script to quickly create new LaTeX documents with corresponding (private) GitHub repository from a Linux terminal.
  • Pieter Belman's GitHub LaTeX template. It comes with a very nice GitHub workflow, which allows you to compile the PDF file directly on GitHub. So you can even edit and compile your TeX files comfortably on your phone.
